Tire tread



FIG. 1 is a front left isometric view of a tire tread showing my new design, it being understood that the pattern is repeated uniformly throughout the circumference of the tread, as shown schematically by solid lines, and that the opposite side isometric view is identical thereto; and,

FIG. 2 is a plan view of the tire tread portion of FIG. 1 projected onto the page.

The broken line showing of a tire inner bead and sidewall is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for tire tread, as shown and described.
